## Phase 7: Hardening, Coverage, And Breaking-Point Tests
Status: started. The first opt-in desktop GPU golden/readback gate now lives in
`pp_renderer_gl_gpu_readback_tests` and is selected by the existing
`desktop-gpu` preset. It creates a tiny desktop OpenGL context, clears to a
deterministic 1x1 red fixture, reads back exact RGBA bytes, and skips with a
clear message when no GPU/context helper is available. The first helper is
Windows/WGL-only; macOS/Linux helpers and broader render golden coverage remain
tracked under `DEBT-0036`.
Goal: tests should try to break components, not only confirm current happy
paths.
